CHARLES B. BARTLEY, OF PITTSBURGH, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TOGEORGE F. RYLANDS, OF CI-IARLEROI, PENNSYLVANIA.

LAMP-BRACKET.

To all whom it may concern:

Be it known that I, CHARLES E. BARTLEY, a citizen of the United States,residing at Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements in Lamp-Brackets, of which the following is a specification.

My invention consists of an improvement in lamp-supporting brackets forminers lamps, and particularly a storage battery lamp.

The object of the invention is'to securely support the lamp upon the capof the wearer and to provide a supporting holder adapted to receive andhold the lamp, to permit of adjustment of it to various angles fordirecting the ray of light, the construc tion by which the lamp iscompletely insulated, and various other features of construction asshall be more fully hereinafter described.

In the drawings: Figure l is a perspective view of the apparatus inposition and provided with a battery lamp. Fig. 2 is a verticalsectional view through the central portion of the bracket, indicated bythe line II. II. of Fig. 3. Fig. 3 is a plan View of the device. Fig. 4is a view in front elevation.

Ordinarily the usual wick lamp commonly used by miners is merelysupported on a forwardly projecting bracket of sheet metal by means of aretaining hook.

In carrying out my invention, I secure upon the cap 2 a bracket 3extending outwardly from the front of the cap, as shown in Fig. 2, andsecured thereon by securing rivets 4, 4, at the top and lower portionrespectively and extensions 5 and 13, to the cap and its vizor, in thesame manner as is customary with brackets for wick lamps. My improvedbracket 3, however, is preferably made entirely of insulating material,as stiff fiber board. The object of such construction is to avoid thepossibility of short circuiting or of injury to the miner by makingcontact by any of the metallic portions of the bracket or lamp withcurrent conducting wires in the roof of the mine, etc.

Fixedly secured to the lower forwardly eX- tending base 5 of the bracket3, by a lower tongue 6 and rivets 7, is the battery holder Specificationof Letters Patent.

8. Said holder is of box-like form having parallel sides terminating atthe front in inwardly directed retaining flanges 9, a back 10, and alower retaining or supporting lip or flange 11, preferably of thin sheetmetal. The back 10 is secured to the lower tongue extension 6 by rivetsor in any other suitable manner, and is also provided at its upper backportion with a rearwardly extending securing lip 01' tongue 12. Saidtongue is provided with a longitudinal slot 13 by which the bracket isadjustably secured to the top horizontal portion of the bracket 3, bymeans of a bolt 14, and terminal thumb nut 15. The connecting rivets areprovided with insulating washers and bushed with insulating materialwherever used, effectually preventing any possibility of passage ofcurrent due to contact with the rivets. The lower supporting tongue 6 isrounded, as at 16, and is sufliciently flexible so that the upperportion of the bracket may be adjusted forwardly or backwardly at anydesired angle and there secured by the bolt and nut 14;, 15. As stated,the bracket 3 being of insulating material, there is no metallicconnection between the lamp supporting case and the bracket 3 at anypoint so that transmission of any current is thus prevented. The innerfront portion of the back 10 of the lamp holder 8 is provided with acleat 17 extending outwardly from the main back and partly severedtherefrom by slots' 18, by which means lamp A is positively retained inposition by means of a resilient tongue or clip 19 (indicated in dottedlines in Fig. 2).

The lamp A, which is of the storage battery type and of any suitableconstruction, is of convenient size and shape to be inserted within theholder 8, resting upon the lip 11, and is retained by the front flanges9 and the clip 19 inserted behind cleat 17, as will be readilyunderstood. By this construction the lamp is firmly secured in positionand may be readily carried upon the cap of the wearer. The tiltingadjustment permits of any desired range of the ray of light to suit theposition or height of the user and to adapt the device to the work inview.

The entire apparatus is comparatively simple and cheap in construction,light and durable, and not liable to get out of order and in practicehas given very satisfactory results.

Having described my invention, What I claim is:

1. In a lamp holder, the combination with a cap, of an insulatingbracket secured to the cap, and a lamp supporting holder and easingmounted on the bracket and electrically insulated from the cap.

2. In a lamp holder, the combination with a cap, of an insulatingbracket secured to the cap, and a lamp supporting holder and easingmounted on the bracket and adjustably secured thereto, and electricallyinsu lated from thecap by said bracket.

8. As an article of manufacture, a bracket for a storage battery lampcomprising a base portion of insulating material shaped to conform andadapted to be secured to a cap, and a lamp supporting holder adapted tocarry a storage battery lamp mounted on said base portion and insulatedthereby, substantially as set forth.

4. As an article of manufacture, a bracket for a storage battery lampcomprising a base portion of insulating material shaped to conform andadapted to be secured to a cap, and a lamp supporting holder adapted tocarry a storage battery lamp mounted on said base portion and insulatedthereby, and having means for adjustably securing it thereto,substantially as set forth.

5. A lamp holder for storage battery lamps consisting of a bracketfixedly secured to a cap, and a lamp holder having a receiving case, alower flexible securing tongue attached to the base of said bracket andan upper rearwardly extending tongue adjust-ably secured to the upperportion of said bracket, substantially as set forth.

6. Alamp holder for storage battery lamps consisting of a bracketfixedly secured to a cap, and a lamp holder having a receiving case, alower flexible securing tongue attached to the base of said bracket, anupper rearwardly extending tongue having a longitudinal slot, and asecuring device for fixedly attaching it to the upper portion of saidbracket, substantially as set forth.

7. In a lamp holder, the combination with a bracket of insulatingmaterial adapted to be mounted on a cap, of a receiving casing for thelamp having a retaining device, a lower securing tongue attached to thebase of the bracket, and an upper rearwardly extending slotted tongueadjustably secured to the upper portion of the bracket, substantially asset forth.

8. In a lamp holder, the combination with a bracket of insulatingmaterial adapted to be mounted on a cap, of a receiving casing for thelamp having a retaining device, a retaining cleat in the inner backportion of the holder, a lower securing tongue attached to the base ofthe bracket, and an upper rearwardly extending slotted tongue adjustablysecured to the upper portion of the bracket, substantially as set forth.

9. The combination with a supporting bracket having a lower forwardlyprojecting portion and an upper rearwardly projecting portion forattachment to a cap, of a casing of sheet metal having a downwardlyextending flexible tongue secured to said bracket, a forwardly andrearwardly extending slotted tongue, a securing bolt, and a casingcarried by said tongues having a back provided with a securing cleat,sides having front terminal flanges, and a lower supporting lip,substantially as set forth.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.
